\ IMPROVEMENT IN BUTTONS.

Specification forming part of Letters Patent No. 202,412, dated April16, 1878; application file March 16, 1878.

To all whom it may concern Be it known that I, SHU'BAEL 00mm, of thecity, county, and State of New York, have invented an Improvement in theConstruction of Collar and Sleeve Buttons, of which the following is aspecification:

The common practice is to make the head, back, and post of collar andsleeve buttons separate, and to unite them by solder. In such case thepost has a seam lengthwise thereof, formed by lapping the edges of theplate from which it is constructed. Skilled labor is required forapplying the solder for the purpose of uniting the head and back to thepost; but the solder is liable to run along the previouslysoldered seamof the post, or else to fail to spread evenly over or around the end ofthe latter. The result is that the back and (more particularly) the headof the button are frequently united to the post so imperfectly that theysoon become detached after the button has been put in use.

In order to form a stronger and more durable (and'also cheaper) button,I propose to construct the post in one piece with the back by strikingup and drawing out the central portion of the latter to the requiredlength, then severing the end of the post and soldering the headthereto. The post having no seam, the solder will not tend to attachitself to the side of the latter, and will firmly unite the parts. Atonestage of the process I upset the hollow post and the disk from which itis formed in such a manner as to increase the thickness of the metal atthe base of the post, therebygradually form a hollow post, A, Figs. 2 to5, inclusive, by raising and drawing out the central portion of thedisk, as Will be readily understood without particular description.

When the disk and post have received the form shown in Fig. 5, I upsetthem by means of dies specially adapted for the purpose, whereby themetal is thickened at the base a of the post A. as shown in Fig. 6. Bythis construction the post is greatly strengthened, and the buttonrendered more durable and serviceable in use. The top of the post isthen sey'ered or out on, as shown in Fig. 7, and the head 0 solderedthereto, Fig. 8. The solder will adhere equally at all points around theend of the post, and thus firmly unite the head thereto.

In forming the post from the disk skilled labor is not required, sincethe several operations are efi'ected by mechanical devices. Less gold isalso required to form the button than when the post is made separatefrom the back, and hence an economy is efl'ected in the manufacture ofthe button.

, I am aware that in the construction of studfastenings for corsets apost has been formed by elongating or drawing out the central portion ofa rectangular plate. I do not, therefore, claim this process.

What I claim is-- 1. The improved process of constructing a collar orsleeve button herein described-to Wit, striking up and drawing out thecentral portion of a circular metal disk to form the hollow post A, thensevering the conical end of said post, and soldering the head 0 to thebody of the same, as shown and described.

2. The collar or sleeve button whose tubular post A and back B areformed in one piece, and having the metal thickened at the base a of thepost, as shown and described, for the purpose specified.
